GI Contract AR-15 Mags

With all the different contracts that were sent out to manufacture these mags, which are the best? I guess I need some explanations on the green followers, teflon coating, and which companies made a more reliable mag.
At one time I found a list on the internet describing all attributes and qualities but have no way to find it again. Can anyone fill me in? Thanks
